It was reported this morning that Diakite had been granted an initial 10-day leave to receive treatment but Diakite has denied that he is depressed.
Diakite told RMC Sport: "I'm fine, I have no problem, I was a bit tired recently, but my club has allowed me to spend three days in Paris.
"But I am not depressed. My club is my employer. I give my best to them every day.
"These reports sadden me because I have received calls of concern from my family. I wanted to reassure my friends and fans of QPR that all is well."
Diakite signed for Queens Park Rangers from Nancy during the summer.
